Talk:Random glucose test

In my edit, I introduced the term "casual blood glucose" which I ran into in an article earlier today. After a closer look at the article, I checked the method used for sample collection and analysis which was as follows:

"Irrespective of the time of last meal, capillary blood was obtained by pricking the index finger. Blood was allowed to drop freely on the test strip already inserted on an Accu-Check glucometer without squeezing the pricked finger. The reading was expressed in mmol/l as the casual blood sugar"[1]. This is consistent with what is known to be the random blood glucose (RBG) test.

Numerous articles that used the same terminology can be found through a PubMed search[2].

I feel confident that this edit is appropriate.BroVic (talk) 15:46, 20 January 2015 (UTC)[reply]


'Random blood glucose test' and 'capillary blood glucose' are not the same thing: random refers to the timing of the last meal (i.e. not fasting), and capillary refers to the sample type (i.e. not blood from a vein, as is ususal). Capillary blood is the blood tested from a fingerprick, measured on a glucometer. A random glucose can be measured in this way or by taking a blood sample from a vein in the arm, then sending it to a lab for analysis. The glucometer method and the lab method use different sample types: the glucometer uses whole blood from a fingertip capillary, and the lab uses plasma separated in a tube from blood taken from a vein. http://www.acb.org.uk/Nat%20Lab%20Med%20Hbk/Glucose.pdf http://labtestsonline.org.uk/understanding/analytes/glucose/tab/glance/ Tietz Textbook of Clinical Chemistry, 5th ed, 2012 205.239.98.30 (talk) 15:14, 17 August 2016 (UTC)[reply]
